With the method Hydrothermal-photosynthesis, respectively prepare mesoporous silica adsorbent with different content of diamine-modified, 5%2N-SBA-15 10%2N-SBA-15 15%2N-SBA-15 20%2N-SBA-15. All mesoporous materials were characterized by X-ray diffraction(XRD), Fourier transform infrared spectroscopy(FT-IR) N2 adsorption-desorption and scanning electron microscopy(SEM). Discuss on how the system factors such as pH value, adsorption time and adsorption temperature affect on the adsorptive property of Pb2+ in the water. The result is that, the optimal adsorption time, adsorption temperature, and pH value, is 60min, 40 , and5, wich means material shows the best performance of Pb2+ adsorption under such condition. The optimal range of content diamine photosynthesised on SBA-15 is 10%~15%.
